Dreamcast forks

Dreamcast Fork Change Report: raylib-dc, GLdc, and dcmesh

This report summarizes the local Dreamcast rendering/tooling fork work since the recorded clone baselines. It is written for maintainers of the Dreamcast raylib/GLdc ecosystem who need to understand what changed, why it changed, and which parts are broadly reusable versus downstream integration glue.

The short version: the forks move the Dreamcast path away from many tiny immediate-mode helper submissions and toward fewer, larger, state-coherent array submissions that GLdc can process through its fastest paths. A small offline mesh format (.dcmesh) was added to pre-stripify static model geometry. GLdc was instrumented and tuned around the same fast path assumptions. SH4ZAM support exists, but the TODO plan correctly treats it as incomplete and in need of a staged follow-up.

Executive Summary

The Dreamcast rendering stack used here is:

LLM Wiki

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

The core idea

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

GitHub Search Syntax for Finding API Keys/Secrets/Tokens

As a security professional, it is important to conduct a thorough reconnaissance. With the increasing use of APIs nowadays, it has become paramount to keep access tokens and other API-related secrets secure in order to prevent leaks. However, despite technological advances, human error remains a factor, and many developers still unknowingly hardcode their API secrets into source code and commit them to public repositories. GitHub, being a widely popular platform for public code repositories, may inadvertently host such leaked secrets. To help identify these vulnerabilities, I have created a comprehensive search list using powerful search syntax that enables the search of thousands of leaked keys and secrets in a single search.

Search Syntax:

(path:*.{File_extension1} OR path:*.{File_extension-N}) AND ({Keyname1} OR {Keyname-N}) AND (({Signature/pattern1} OR {Signature/pattern-N}) AND ({PlatformTag1} OR {PlatformTag-N}))

Examples:

 オレは高校生シェル芸人 sudo 新一。幼馴染で同級生の more 利蘭と遊園地に遊びに行って、黒ずくめの男の怪しげな rm -rf / 現場を目撃した。端末をみるのに夢中になっていた俺は、背後から近づいてきたもう1人の --no-preserve-root オプションに気づかなかった。 俺はその男に毒薬を飲まされ、目が覚めたら・・・ OS のプリインストールから除かれてしまっていた!

 上田博士の助言で正体を隠すことにした俺は、 which に名前を聞かれて、とっさに『gnuplot』と名乗り、奴らの情報をつかむために、父親がシェル芸人をやっている蘭の $HOME に転がり込んだ。ところが、このおっちゃん・・・とんだヘボシェル芸人で、見かねた俺はおっちゃんになりかわり、持ち前の権限昇格能力で、次々と難タスクを解決してきた。おかげで、おっちゃんは今や世間に名を知られた名エンジニア、俺はといえばシェル芸 bot のおもちゃに逆戻り。クラスメートの convertojichattextimg にお絵かきコマンドと誤解され少年ワンライナーお絵かき団を結成させられる始末。

My Docker Swarm Architecture

This (and related gists) captures how i created my docker swarm architecture. This is intended mostly for my own notes incase i need to re-creeate anything later! As such expect some typos and possibly even an error...

Installation Step-by-Step

Each major task has its own gist, this is to help with maitainability long term.

  1. Install Debian VM for each docker host
  2. install Docker
  3. Configure Docker Swarm
  4. Install Portainer
  5. Install KeepaliveD
  6. Using VirtioFS backed by CephFS for bind mounts (migrating from glsuterFS - WIP)
